public class Projector extends ProxyReceiver
PathMap to do document projection.
It acts as a push filter, passing through only those events that are necessary
to evaluate the expression that was used to generate the PathMap.nextReceiverpipelineConfiguration, previousAtomic, systemIdPI_DISABLE_OUTPUT_ESCAPING, PI_ENABLE_OUTPUT_ESCAPING| Constructor and Description |
